I also found a few that have different meanings in the same country/region... such as quenelles (which is a dish made of poached pâte à choux) for example.. not sure if you are interested in those here?

The French tacos are a newer thing... past 10 years or so... here's an example of a menu. The tacos look open on the menu so you can see the fillings (including french fries) but they are served closed like a burrito that was then pressed/grilled like a panini. For a laugh, check out the TexMex menu at the bottom. Click the pic to see it in big:
